Patent GB-553062-A (GB)
Title: Means for treating and feeding material
IPC: F27B7/20
Filed: 1941-09-23
Abstract: 553,062. Drying and heating materials. KENNEDY, J. E. Sept. 23, 1941, No. 12317. [Class 78 (i)] [Also in Group XII] Apparatus for utilising furnace gases for drying and preheating material to be passed through the furnace, e.g. limestone or coal, comprises a bin B leading to a casing C the bottom of which leads to a hopper 10 fitted with a shoot 12 which conducts the material to a rotary or other furnace 3. A suction fan F draws the gases from the furnace into a housing 4 whence they proceed by way of a conduit 24 to openings 22 in the lower part of the casing C. Leading from the openings 22 into the casing C are inclined inverted V-shaped channels 31 which diminish in cross-sectional area toward their upper ends. Located above these channels in laterally staggered relation, are two rows 32, 33 of inverted V-channels which increase in area toward their upper ends and lead to outlets 28<SP>1</SP>, 28. The outlet 28<SP>1</SP> communicates with a duct 27 from the outlet 28 to take the gases by way of a separator S to the fan F and thence to a stack 6. The housing 4 is connected directly with the base of the stack 6 by a passage 5 controlled by a manually operated damper 7. Between the outlet 28<SP>1</SP> and the duct 27 is a pivoted valve 34 controlled automatically through thermo-electric means by the temperature of the gases leaving the fan F. The damper 7 and valve 34 thus provide means for adjusting the degree of drying and heating imparted to the material in its passage down through the casing C. The downward fall of the material is effected and controlled by a grid 18 of horizontal bars which is reciprocated by power means over a grating formed of parallel elongated platforms 14 separated by narrow gaps, the bars serving to push the material first one way and then the other into the gaps. Located over the medial lines of the platforms 14 and over the gaps is a series of stationary triangular baffles 15 which direct the material on to the edges of the platforms 14, and between which and the platforms the grid 18 moves. The reciprocation is effected by an eccentric adjustable to vary the stroke. The shoot 12 may have a hollow wall through which a cooling fluid, such as air, is sucked by the fan F. The separator S consists of a cylindrical chamber into which the duct 27 leads tangentially, the gases passing spirally downward and then rising through a tube 41 to the fan F. Matter deposited from the gases collects in a lower cone and can be abstracted by way of a valve.

Title: Improvements in heat exchangers for treating viscous substances
IPC: A23D7/05
Filed: 1953-05-04
Abstract: 739,288. Plate heat-exchangers. AKTIESELSKABET ATLAS. May 4, 1953 [May 3, 1952], No. 12367/53. Class 64 (3). Relates to a heat-exchanger as described in Specification 644,312, for heating or cooling viscous substances such as fatty emulsions &c., in which heating or cooling medium flows through stationary containers 1 while discs 12 bearing scrapers 23, Figs. 2, 3, rotate between the containers in spaces 11 through which the treated substance flows under pressure. In Fig. 2, three resilient scrapers 23 are indicated on each side of a disc 12. According to the invention, to avoid bending of the discs due to accumulation of viscous substance in front of the scrapers, there are projections 26 on one or both sides of the discs, the ends of which projections move very near to the walls 6 of the containers 1, and there are holes 25 in all or some of the scrapers. These holes and projections may be embodied in the upper discs 12 only where the viscosity has increased. The dished side walls 6 form the spaces 11 containing the discs 12. The heating or cooling medium enters an inlet on the lowermost container 1 and flows, by way of similar outlets and inlets 16, in series through the containers which are each divided into an upper and a lower compartment by a partition 14 having holes 15 near the middle and bearing ribs 18, e.g. forming spiral channels in which the medium flows. From the top container the medium flows out through a duct 17 formed by sections on each container. The viscous substance flows from an inlet 22 to an outlet duct 24 at the top, through each space 11  around each stainless-steel disc 12 and through central spaces in which rotate the hubs of the discs 12 where they are keyed to a shaft 10 driven by worm gearing 20. Cooling medium may be supplied to some containers 1 and heating medium to others.

Title: Improvements in or relating to methods of manufacturing shadow masks for cathode ray tubes
Inventor: HAUSER ERWIN
IPC: H01J9/14
Filed: 1965-03-24
Abstract: 1,111,582. Colour television tubes. MULLARD Ltd. 2 March, 1966 [24 March, 1965], No. 12453/65. Heading H1D. [Also in Division B3] A shadow mask for a colour television tube is made by a photoresist method involving the use of a photographic transparency which is formed by exposure to an illuminated aperture through a transparent cross-line screen in a system constituting a multi-aperture stenopaic system, i.e. a system in which the exposed areas or images are in the shape of the illuminated aperture, e.g. circular, rather than in the shape of the apertures of the cross-line screen. These apertures may, however, be rhomboid shaped in the case of a delta-arranged three-gun tube and may be circular or hexagonal to allow a certain latitude in the placement of the cross-line screen. A photographic transparency may be applied to each photographically sensitized side of a blank which is to form the shadow mask and the blank exposed and etched from both sides. Uniformly sized areas may be etched on one side of the blank and areas radially decreasing in size on the other so that holes are formed which assume an increasingly conical shape towards the edge of the shadow mask.

Title: Heat-sealed packages
IPC: B65D77/20
Filed: 1976-06-21
Abstract: 1536428 Seaming non-metallic sheet material BACOFOIL Ltd 21 June 1976 [26 March 1975] 12662/75 Heading B5K A peelable heat-seal is formed between two package-forming members 10, 12 one of which comprises a laminate 10 having a thermoplastic polymeric ply 16 fused to an area of the member 12, the tensile strengths being such that on peel-opening the package the fused parts of the members 10, 12 stay united with the member 12. In one embodiment, Fig. 2, a package containing a scalpel blade 20 comprises two pieces 10/12 of a laminate comprising an aluminium foil ply 14 having a high density polyethylene film 16 bonded thereto by a polyurethane adhesive 18. The pieces 10, 12 may be separate sheets or may be integral with each other, i.e. a single folded sheet. One end of the piece 12 is longer than that end of the piece 10 to form a tab to facilitate peeling open the package. The pieces 10, 12 with the blade 20 therebetween are heat sealed together by heat and pressure applied between two jaws the upper one of which has a projecting heat sealing iron in the shape of the desired seal. The pressure is controlled so that the central body 28 of the fused plies 16 has a thickness greater than a single ply 16 so that the strength of the body 28 is greater than the strength of the bond between the body 28 and the outer ply 14 of the piece 10. This results in, upon peeling the piece 10 from the piece 12, the body 28 breaks away from the ply 14 of the piece 10, Fig. 3. In another embodiment, Fig. 5, a closure 44, comprising a high density polyethylene film 48 bonded by a polyurethane adhesive to an aluminium foil 46, is heat sealed to the rim of a moulded high-density polyethylene bottle. Upon peeling the closure 44 from the bottle by a lifting tab 50 parts of the film 48 remain adhered to the bottle rim, as shown. Alternatively, the bottle is formed of a mixture of 50% high density and 50% low density polyethylene and the film 48 may comprise either high or low density polyethylene. In modifications, (a) the thermoplastic ply of the laminate is extruded directly on to the other ply without the use of polyurethane adhesive; (b) the polymeric material of the first member comprises low density polyethylene and the second member comprises, by weight, 50% high density polyethylene and 50% low density polyethylene; (c) the polymeric material is polypropylene; and (d) the aluminium foil ply is replaced by a layer or film of thermoplastic polymeric material having a softening temperature higher than that of the polymeric material effecting the seal.
